NEW DELHI: BJP today joined issue with the government on the interpretation of the Supreme Court judgement on natural resources allocation, saying no attempt should be made to use the judgement to justify "wrong" decisions and "malign or forewarn" constitutional authorities.

Batting for CAG without naming it, BJP attacked the Union Cabinet ministers who had said yesterday that the Supreme Court observation about auction not being the sole method of allocation of natural resources vindicated their stand. The ministers had also said CAG should keep this mind while doing its job.

"I hope that there is no attempt by the union ministers to interprete this Supreme Court judgement in their favour just to justify their wrong policy decisions.... To malign, to forewarn, or to caution a constitutional authority is an unacceptable and condemnable practice which the government should not indulge in," BJP spokesperson Nirmala Sitharaman said.

She said the government should not use the "advisory" of the apex court to "whip another constitutional authority".

"Every constitutional authority in the country is doing its job... And the courts are there to deal with it (any breach of their responsibility)," Sitharaman said.

The party expressed surprise at the interpretation arrived at by the union ministers and said the judgement was quite "explicit" in stating that auction and competitive bidding were the way to go in all cases of commercial exploitation of natural resources.

"They (the ministers) have gone on a elaborate way to talk about it. BJP finds this again an attempt by the union ministers- and earlier the Prime Minister himself was on board on this- commenting on another constitutional authority," Sitharaman said.
